Welding preheating and postheating are an important application area of induction heating. After preheating steel, welding can reduce stress, improve welding strength, and prevent cracking. Postheating is used for hydrogen elimination, annealing, tempering, normalizing and other processes.

Induction heating is used for pre-heating and post-heating of welding. It has the characteristics of good controllability, complex technological procedures, non-contact heating, wide application range, high efficiency and energy saving, high energy density, and online heating.

The “DSP + IGBT + reactance analysis method” of science and technology is a full air-cooled temperature-controlled induction heating power supply, which is especially suitable for the pre-heating and post-heating of welding with high requirements.

Features
